help i recently purchased a bambu lab P1S with AMS and it sropped printing in the middle of a print job. The error that it returned said that the print head cover was possibly loose. i then checked the cover, looked for loose wire connections but everyhig was fime. i then selected resume , the error disappeared in studio so i then shut off the machine from the power switch on the back . when i turn the printer back on the fan ran for a few seconds then everything except the lcd display went dead. chat gpt suggested i replace the heat end and thermistet which i was planning to do tomorrow. Any other suggests would be apprieciated thanks
